Abstract

Preparation of para-substituted 4-hydroxybenzophenones by forming poly(4-oxybenzoyl) in situ and reacting it with an appropriately substituted aromatic compound. The poly(4- oxybenzoyl) can be formed from a precursor such as 4-hydroxybenzoic acid by reaction with an agent which removes water from the acid to form the polymer. The reaction with the appropriately substituted aromatic compound, for example fluorobenzone, is effected in the presence of a Lewis acid compound such as aluminium chloride.
